ATTACHMENT FOR BAG-MAKING MACHINES.

To 0/! whom it may concern:

lie it known that 1, Leon F. BAUMANN, a citizen of the United States, residing at Fitzdale in the county of Essex and State of Vermont, have invented new and useful lmprovernents in Attachments for BaghIaking-Wlachines, of which the following is a specification.

This invention relates generally to machines wherein use is made of a paste roller for supplying the product of the machine with paste for an adhesive substance, the invention being shown and described in connection with. the bag-making machine, although its general application is contemplated by the claims.

In a machine of this character the paste roller operates within a container for paste or other adhesive substances, and a considcrable portion of the paste taken up by the roll is thrown therefrom incident to centrifugal force. This results in the waste of the adhesive substance, clogging of the working portions of the machine and a decrease in production.

It is therefore the purpose of this invention to provide a means to overcome these objections. by collecting the substance thrown from the paste roll in the manner above described, and returning it to the container for the same.

To this end use is made of a roll arranged in juxtaposition to the paste roll to catch the substance thrown from the latter incident to centrifugal force, with means for scraping the said roll and returning the surplus paste or adhesive substance to the container therefor, thereby eliminating waste, as well as permitting the machine a higher rate of speed with an increase of production.

The nature and advantages of this invention will be better understood when the following detail description is read in connection with accompanying drawings which form part of this application.

In the drawings forming part of this application like numerals of reference inch-- cate the similar parts in the several views and wherein z- Figure 1 is a side elevationv of a machine with which the attachment is used,- showing the attachment in position for use.

an old and well known construction, and it,

has been found that a considerable quantity of the paste or the like taken from the container 10 by the roll 11 is thrown from the container by centrifugal force which results, not only in fouling the working parts of the machine with a consequent reduction in efliciency, but also resultsin the waste of this surplus paste. I

The present invention embodies a 'roll 13 disposed in juxtaposition to the .paste roll 11 to collect the surplus paste thrown from the roll 11 incident to centrifugal force. The roll 13 is preferably arranged immediately above and slightly; in advance of the paste roll 11, occupying a position so that the paste thrown from the roll 11 will strike the roll 13. A belt 14 is utilized to rotate the roll 13 in a direction away from the roll 11 although any other suitable means may be employed for this purpose. Projecting from a fixed part of the machine is a scraper 15 curved over the roll 13 and terminating to provide a flange 16 which bears against the periphery of the roll 13, so that as the latter is rotated, the paste or adhesive substance taken by the roll 13 is removed therefrom and allowed to gravitate back into the container 10.

Vhile it is believed from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that gI do not limit myself to what is here-in shown and described, and that such changes may be resorted to as fall within the scope of what is claimed.

What I claim is 1. In a machine of the class described the combination with a paste roll, of an additional roll arranged in juxtaposition to the aste roll to collect the paste thrown there-' rom by centrifugal force, means for 1'0- 1' ,tating the latter mentioned roll and a scraper for said r011.

2. In a machine of the class described, the combination With a pastecontainer and a paste roll operated within the latter, of an additional r011 arranged adjacent the paste roll to receive the paste thrown from the latter by centrifugal force, means for rotating said additional roll, a scraper including a member curved over said addi- 10 tional roll and having one end bearing against the latter to remove the paste therefrom, said scraper being designed to direct the said paste intosaid container.

In testimony whereof I aflix my signature. 15
